This site is a measuring instrument, and it treats visitors the way it treats data: it keeps only what it can justify.
No accounts, no API keys, no cookies set by us, no advertising or tracking pixels, no fingerprinting, no sale or sharing of any visitor data. The MCP endpoint and every dataset are free and anonymous by design.
For each tool call the server records the tool name, argument shapes, latency and result size, keyed to a session hash that is derived with a weekly-rotating key — IP addresses are never stored in analytics, and hashes are unlinkable across weeks. Purpose: finding failure modes so agents get better answers. Detail rows are deleted after 90 days. A narrow allowlist of low-risk values is kept (product search phrases, country and chapter names) to fix vocabulary gaps.
Traffic passes through Cloudflare, which processes IP addresses transiently for security and caching under its own policies. The origin server is in the United States (Ashburn, Virginia).
